Coverage

Smooth: 80-120 sq ft/L। Rough: 50-80। Always 2 coats। 200 sq ft: ~5-6L। Asian Paints WoodTech, Pidilite: popular brands। Indian climate needs UV + moisture protection।

Teak Care

Teak oil for indoor furniture: best protection। Outdoor: marine varnish। Reapply outdoor annually (monsoon damage)।

⚡ CalcWolf Insight

The single biggest staining mistake: not cleaning and prepping the surface. Stain applied over dirt, mildew, or old flaking stain will peel within a year. Power wash, let dry completely (48+ hours), and sand smooth before staining. Prep is 70% of the job — the actual staining is the easy part.
